SAFE-.FASTEN ER.

SPECIFICATION forming part of Letters Patent No. 393,289, dated November 20, 1888.

Application filed August 24, 1888. Serial No. 2S3,6:2l. (No model.) Patented in France May 18, 1885, No. 168,991.

To aZZ whom it may concern,.-

Beit known that I, LoUIs ALBERT BECHT, a citizen of France, residing at Paris, in the Department ofthe Seine, France, have invented a new and useful Improvement in the Construction of Safe-Fasteners, (for which I. have obtained French Patent No. 168,991, dated May 18, 1885,) of which the following is a specification.

This invention relates to means for holding the doors of metal safes,bankvaults,and other receptacles for valuables, closed against the effort to force the same by removing the door from its hinges.

One mode of forcing safes consists in introducing wedges by means of special tools between the door and the side frames,and to operate the Wedges in such way as to separate the i1prights,which are often only illy secured by cross-pieces simply laid against the uprights. The door in this case serves as a point of resistance on both sides to the efforts by which a sufficient separation for the door to be opened may often without much difficulty be produced.

In accordance with the present invention the door itself is utilized as a cross-connection to prevent the separation ofthe side frames in case attempt is made to force the safe by this mode.

In the accompanying drawings, Figure 1 is a horizontal section through a safedoor and door-frame of a safe provided with the present improvements, and Fig. 2 a partial view showing a duplication of some of the parts.

M and N are the opposite sides of the opening orframefor thedoor,which turnsupon the pivot l?, and is locked by the bolt p of the lock S.

rlhe door X Y Z Vand the side frames,A B, are constructed in the following manner: The part X of the door corresponding to the side of the opening away from the hinges is provided on the inside with a proj ection,0, transverse to the plane of the door and terminating in a hook, d, which in the normal position u of the parts with the door closed, as shown,

faces the corresponding hook, e, on a projection, C', from the metal piece A, which projection C extends around the projection C, leaving a space for the latter between itself and the door-frame A. Said piece A is firmly secured on one side to theeXterior casing, t, of the safe, and riveted on the other at f to the lining a.

From the relative position of the two projections O C and hooks d e it will be understood that if, in consequence of efforts applied at the `crack Z, the part A has been pushed a little to front will also be without result,because of the v position of the two parts d e, which hook together and hold the door perfectly. Therefore, by these dispositions, which 'form part of my invention,` and which provide a projection suitably placed on the inside of the door in correspondence with a suitable projection on the body of the safe, a double retention is effected,whereby the openingof the safe by separating the door-frame at the left, A,is rendered impossible. To oppose like efforts which may be applied at the side of the pivot of the doornamely,effortstendingto forceasidethe upright B-the junction o between the door and frame is made in section,as shown at p g r s, there being a dovetail recess, q r, in the frame, and a smaller dovetail extension, p s,on the abutting edges of the door,which extension enters said recess, as shown. The projections p q assure the engagement of the right upright, B, by the door, and the projections r s contribute to arrest the separationin case the first efforts have resulted in a small displacement of the upright B, which in being moved will be brought a little in advance to bring the projections r s into engagement. A third retention of the door is thus secured.

It is designed to use, if desired, only a part of the new fastening means described. Any suitable means can be used to secure to the rest of the safe-body the pieces A B, which the door engages in order to prevent burglars opening it in the manner described, such means being accessory only to the invention.

The hooks d e, which are parallel with the door and overlap when the hooks engage, are undercut, so as to present an increased resistance to sliding.

ICO

For the sakeof simplicity the invention has been described as applied to a safe; but it may be appied generally where great security is required.

The number of points at which the door engages the door-frame may be varied--as, for example, by placing near together two or more pieces, C, on the door, corresponding to two or more pieces, C', on the body of the safe or fixed portion to be engaged by the door, as shown (for two pieces) in Fig. 2.

I claiml. A safe or other door provided with a hooked projection on the inside transverse to the plane ofthe door,in combination with the door-frame andastationaryhooked-projection, the two projections overlapping when the door is closed, and having their hooks turned toward each other and undercut on the faces which are parallel with the door,substantially as described.

2. A safe or other door turning on a pivot,

and having on the edge adjacent to the pivot and inside the door a dovetail extension transverse to the plane of the door,in combination with a door-frame provided with a transverse dovetail recess Wider than said extensiomsnbstantially as described.

3. In combination with a door-frame provided With a stationary hooked projection at one side and with a dovetail recess at the side opposite, a door having a corresponding hooked projection which enters between the rst-narned projection and the door-frame, and a dovetail extension which enters the aforesaid reccss in said fraaie, substantiall y as described.

In testimony WhereofI have signed this specifcation in the presence of two subscribing witnesses.

LOUIS ALBERT RECHT.
